SQL SERVER – Fix : Management Studio Error : Saving Changes in not permitted. The changes you have made require the following tables to be dropped and

I encountered problem when modifying table in SQL Server 2008, Once the table is created open the table in SSMS by clicking on the table name and selecting “Design.” Try to include another column to the existing table and click on save (CTRL+S). It will prevent it from saving and will emit the following error in popup.
Saving Changes in not permitted. The changes you have made require the following tables to be dropped and re-created. You have either made changes to a table that can’t be re-created or enabled the option Prevent saving changes that require the table to be re-created
